For the original clear potted regulators, that behavior is almost considered normal. The replacement should be better. A shorted or badly discharged battery might aggravate the problem, but you would expect the same battery to have trouble starting the engine.

hope it helps

Re: voltage regulater burning

Sounds like either the regulator/rectifier assembly has failed, just because its time had come, or perhaps the battery cables got swapped and the reg/rect was fried.

Check your batt cables to make sure they're connected with the correct polarity.

Having batt cables swapped for just a moment will instantly fry a reg/rect.

Either way, don't run it any more, fires inside an outboard are not something you wanna see!! :0
